OTTO KAUFMAN, OF YOUNGSTOWN, OHIO.

To all whom it may concern:

Be it known that'I, O'rro KAUFMAN, a citizen of the United States,residing at the city of Youngstown, county of Mahonmg, State of Ohio,and whose post-oflice address is care of the Block Light 00., in saidcity, have made a new and useful Improvement in Mantle-Cutting Machines,of which the following is a specification.

My invention relates to a machine for severing mantle blanks from acontinuous weblor stocking so that each blank. will be of the desiredlength. As many blanks may be simultaneously severed as there are websand one or more webs may be run through the machine at one time it beingunderstood,

however, that in the em odiment of my ma-' chine hereinafter set forth,the severed portions will be of the same length. The action of themachine is entirely automatic throughout and requires noattention, savethe general supervision more or less necessary for all automaticmachines.

For a further description of my invention, reference is to be had to theaccompanying drawings, forming a part hereof, in which Figure 1 is aside elevation of a machine Fig. 2 is a top plan view of the same. Fig.3is a rear elevation of the machine. Fig. 4 is a frontelevation of thesame. Fig. 5 is a sectional view taken on line '5-5 of Fig. 2, lookingin the direction of the arrows. Fig. 6 is a sec tional view of themachine taken on line '66 of Fig. 2, looking in the direction of thearrows. Fig. 7 is a sectional view showing the cutter and a part of itsdriving mechanism. Fig. 8 is a sectional view taken on the line 8-8 ofFig. 7, looking in the direction of the arrows. Figs. 9-12 inclusiveshow a c'am for elevating or depressing the cutter and the rollerdooperating'therewith, Figs. 9 and 10 showing the cam in the positionwhere it elevates the rollerand Figs. 11,

the spools or bobbins 8 are -mounted that carry suitable. mantle webs 9.Two of these spools are shown, and it is obvious that more may be usedby simply increasing the number of standards or, ifdesire'd, onlyone-web need be used, according to the desires of the operator. The webs9 pass under-a suitable and horizontally disposed bar 10 which forms aguide transversely of the direction fed into the machine. This bar 10 iscarried by suitable standards 11, one near each end, which rise fromtheplate 12 that is carried by suitable sides 13 from the table 3. The

web 9 then passes between suitablevertical Y guides 1-1, each' of whichis provided with a rod 15 that runs into a standard 16, where it may beclamped bymeans of a suitable set screw 17 in any desired positionwithin its range of adjustment. The object of the vertical guides 14 isto cause the webs 9 to be properly placed between the feed rollers 18and 19, which will be described below. The

plate 12 is suitably slotted, so as to permit the lower'roller 19 topass through this plate hi hest line will be a little above the level otthe plate 12. This plate is also slotted at 20, so as to permit a cutter21 to pass through the same at the desired interval.

. The feed 1-0Zle1's.The feed rollers 18 and 19 are mounted so as to bedriven together as will appear below. These rollers have their journalsrunning through suitable bearings 22,, which are so arranged anddesigned that'the'se rollers are normally kept in contact by the tensionof springs 23 placed under. Suitable caps 24, one spr ng and cap foreach bearing 22 and the tens on is adjusted by means of screws 25applied to these caps and uniting them with the bearings- This tensionenables the rolls 18 and 19 to firmly grip the web 9, which s fedtherethrough and feed the same whenever these rollers are rotated. Therollers have to move in .u hison, because they are of the same diameterand they are geared together by identical pinions 26 and 27, the pinion26 being connected to the roller 18 and the pinion 27 to the roller 19.The roller 19 1s also connected, at the other end, to another pinion 28,which is fixed to the journal shaft of this roller'and outside thebearing 22 and this pinion 28 meshes with an idle gear 29, mounted on astud 'shaftBO in a bracket 31, one end of which is mounted on a studshaft 65 I of the movement of'the web 9 when being .i

-. The gear '34 meshes with a corresponding gear 35 fixed to a suitableshaft 36, which is mounted in the supports 13 in any suitable bearingsand this shaft 36 may be considered the main shaft of the machine. It isdriven by a suitable sprocket wheel 37,

which is fixed -to this shaft 36 in any suit- 1 able manner and thissprocket wheel is driven by any suitable sprocket; chain, not

- shown. The bracket 31 is provided with a suitable'arm 38 that projectsdownwardly and in such a manner that its central slot is concentric withthe axis of the shaft 32. A suitable bolt 39 mounted on the frame of themachine passes through the slot in the 'projection 38 and enables theoperatorto adjust the bracket 31 in any desired position. This positionwill vary with the length of the mantle to be severed, because the gearsas shown canoperate for only one length of mantle and when a mantle ofa. different length is to be severed, the gears may be correspondimglychanged, so as to give the rollers 18 and 19 a greater or less angularmovement for each shifting of the cutter 21, as is obvious.

The 0Zamp.By referring to Fig. 5, it will be seen that the main shaft 36carries a suitable cam 41, which runs against and controls a roller 42,mounted on a suitable spindle 43, fixed to a shaft 44 running at rightangles thereto and journaled in one of the supports-l3. 'This shaft 44(see Fig. 6) carries a suitable segmental gear 45, which meshes with acorresponding gear 46, mounted loosely on a suitable shaft 47, whichwill be described below. The gears 45 and 46 are identical and each hasteeth .meshing with racks 48 and 49, respectively, on suitable standards50 and 51 that pass through ears or guides 52 secured to the standards13. These standards 50 and 51 are each provided with suitable coiledsprings 53, which are depressed when these rods are lowered, and attheir tops, these posts are united by suitable angle bars 54 and 55connected by a crossing 56. The free ends of these bars 54 and 55,respectively, are provided with downwardly extending rods 57 and 58,which have suitable nuts 59 and each runs from 'a suitable sleeve 60just below the nut 59 and below the angle bars 54 and 55 are suitablecoiled springs 61, which press against suitable nuts 62. Below the.

nuts and within them the rods 57 and 58 are screw threaded and securedto a suitable presser foot or stripper 63, which is slotted at 64, so asto permit the cutter 21 to extend through the slot 20 and into a slot64, so

the presser foot 44 so that it clamps the fabric in place over thecutter 21 and this cam 41 is so shaped that the clamps the fabric allthe time the cutter 21 is in operation and nearly all the time that therollers 18 and 19 are idle.

resser foot The cutter.--By turning to Figs. 7 to 12 inclusive, it iseasy to understand the action of the cutter 21. This cutter 21 iselevated and depressed by mechanism driven from i the shaft 36, which isprovided with a suitable cam for this purpose. This cam 65 is arrangedto raise and lower a corresponding roller 66, mounted on a suitablestudshaft 67 fixed to a shaft 47 above described, which is journaled ina suitable bearing 68 that runs from a side 13. The shaft 47 is alsofixed, to an. arm 69, the outer end of which is slotted to engage a pin70 on a suitable support 71, which'runs to a shaft 72, on which. it isloosely mounted, so that the shaft 72 can rotate therein. This shaft 72is mounted in a side 13 and is driven at a high speed by a suitablepulley 73, which is fixed to this shaft and receives a belt from anysuitable source, not shown. .The cutter-'21 is mounted on a suitablemandrel 74 in the conventional manner and this mandrel 74' is providedwith a suitable groove 75 to receive a belt or cord 76, thatruns to apulley 77 fixed on the shaft 72, so that the cutter 21 is rotated at ahigh velocity and driven from the shaft 72. It will be noted that thecam 65 is made, so as to elevate'the roller 66 for a shorter time thanthe cam 41 elevates the roller 42, so that the elevation of the cutter21, above described, is for a shorter period than the depression of thepresser foot or stripper 63.

Operatiom-In view of the foregoing, the operation of my improved mantlecutting machine will be readily understood. Assuming the parts to be asshown in. Fig. 1, (except some parts are omitted, as is obvious, to moreclearlyreveal the structure) and power is applied to the sprocket wheel37 and the pulley 7 3, the mantle web or webs 9 are then passed underthe guide 10 and between the guides 14 to the rollers 18 and 19, whichintermittently move the web under the clamp 64, where it is clamped andwhile so clamped, the cutter 21 rises and severe the fabrics andimmediately retires. The clamp is then removed, the feed rollers 18 and19 again have an angular movement for a predetermined distance, feedinga predetermined length of fabric under the clamp 64 and when thismovement ceases, the clamp is depressed, the cutter 21 rises and or forthe various length of mantles, whichmay be desired.

Whilel have shown and described one embodiment of my invention, it isobvious that it is not restricted thereto, but that it is broad enoughto cover all structures that come within the scope of the annexedclaims.
